According to folks I talked to during the event, the course changes a little bit every year.

Also, one frustrating aspect to the event is that course I showed you wasn't available until about 3-4 days before the event, which doesn't leave you with the most amount of time to preview what you have ahead of you, at least that's the case for me since I have a 9-5 to deal with.

If you happen to do the event in 2019, major props to you. Hopefully you have a GPS biking device handy as you'll need all the help you can get to avoid getting lost.
